In this research, the effect of radiation dose on thermal and mechanical properties of polymer blends between poly(lactic acid) (PLA) and poly(butylene succinate) (PBS) were determined at the PLA/PBS weight ratios of 100/0, 80/20, and 0/100. Dicumyl peroxide (DCP) was used as additive at 0.2 phr. The radiation doses were varied at 0-150 kGy. There were some changes of chemical structure upon irradiation as observed via Fourier Transform Infrared Spectrometer (FT-IR), leading to the decrease of melting temperature (T m ) with the increase of radiation doses. Moreover, the flexural strength determined via Universal Testing Machine (UTM) were decreased with increasing radiation doses. The lowest biodegradation was found at the radiation dose of 50 kGy.
